I'm using FlashBuilder 4.6, with Flex SDK version 4.6.0 (build 23201), playerglobal.swc (current one from Adobe's page, http://www.adobe.com/support/flashplayer/downloads.html, said to be 11.2 as well), the standalone debugger projector (11.2.202.228) and same browser flash player plugin (11.2.202.228), so by my reckoning, I'm up to date in everywhere I should be, but, if I do

While ya coulda been a bit more informative, you are right. I had swf-version at 13, but it needed to be all the way up to 15 for 11.2 stuff. Disappointing from me, but I do think Adobe could put that stuff in the docs too. When you're not paying 100% attention, there's always things like this that you can miss out on. In the docs, they have which versions of AIR have that property / functionality and same for the Flash Player, but if there's a min-spec for the swf-version, could that not be stated too?
